SHACKLE ron AUTOMOBILE-WHEELS AND sroKEs.

T 0 all whom it may concer'n:

Be it knownthatl, EARLE E CI-IAPMAN, av citizen of the United States,residingat LosAngeles, Los Angeles County, California, have invented a new and useful Improvement Comprising the Shackle for Automobile Wheels and Spokes, of which theto provide a shackle for this purposewhichwillmake an unmistakable sound, preventing the automobile from running at a hlgh speed, and

'which will also leave a distinctive mark on the surface of the street in case the. automobile is driven with the shackle in the place on the wheel thereof. For this purpose I provide a bumping member which is secured on'the tread of a tire and provided with a sharp projection so placed as to dig into the street if the automobile is moved with the shackle in place. 'f r V v A further object of the invention is to provide a device whichin addition to lockingabout the tire and fellv of the wheel,

will also lockabout a spoke so that the shackle cannot be turned around on the tire to put-the projection or bumpingmember out of action.

A. still further object of the invention is. to so construct the parts which lock about.

the spoke that they will be swivele d from collar 29 on the projection 25 is alocking the shackle in such a manner that the spoke will not be injuredin case the automobile is I illustrative purposes only, 1 is a view' of the wheel of an automobile with a shackle in place thereon.

lingers in the position they assume when packed for shipment.- 1

Fig. 3 is a side'view of same showing the fingers in the position they assume when in place on the tire of an automobile.

Fi 4 is a view showin a shackle 0011- structed similar to the'one shown in Figs. 2

and 3, except that the locking fingers are dove-tailed together.

,Fig. 5 shows a, shackle using a one piece locking clamp. I

Fig. shows a view of a shackle: hav'ng double ended clamps. i F' is a view of a shackle provided with a chain for locking about a spoke and Fig 9 shows this shackle in place on a wheel.

All of these forms of shackle are designed V to go over a tire 11, carried on a wheel 12 having a felly13 and-a series of spokes 14:; Each of the shackles illustrated comprises a bumpingblock 20having a pointed projection 21 which is so shaped that it will make;

a distinctive mark on the street in casethe automobile is run with the shackle in place as shownin Fig. 1..

Extending upwardly from one side of the bumping block 20 is an arm 22 which terminates in'aprojection' 23 wl1ich extends inside the felly 13 of the wheel when the shackle is in place thereon. A M

.Anarm 24 pivoted'on a .pin 15on the bumping block 20 extends up and has projection 25carr'ying a lock 26, the lock 26 looking the. projections 23 and 25 together whenthe shackle is in place on the wheel.

.P'rojections 23 and 25 are preferably cylindrical. Mounted toturn freely on the projection 23 but restrained by axialimovement thereon bycollar 27 is a' locking finger 28 and similarly securedby means of a locking finger 30. a The fingers 28 and 30 are free to a very compact package but bein turned out in position shown in full lines 1n Fig. 3

and in Fig. 1 when the shackle is secure upon a wheel.

It will benoted that the shackle can turnfrom the ullline position shown in Fig. .1

to either of the dotted positions shown in that figure without exerting any wedging or jamming action on the spoke. It the fingers 28 and 30 were formed or rigidly secured on the shackle any movement of the shackle from the full line position shown in Fig. 1 to either of the dotted line positions in that figure would result in the fingers 28 and 30 digging into the spoke of the wheel thus cutting thru the paint and defacing the spoke to a very unsightly degree. I By pivoting the fingers 2'8 and 30 so that they can turn about the projections 23 and 25, I am thus able to not only provide a compact shipping package, but I also provide a shackle which will not mar a spoke even if the wheel is turned with the shackle in place.

In practice the shackle is put in place by unlocking the projections 23 and and swinging the arm 2% with its ger to the position shown in dotted line in Fi g. 2, the shackle then being put over the wheels and fingers 28 and 30 being turned to engage a spoke previous to closing the arm 24 and locking the members and 25 together.

For the purpose of insuring the fingers 28 and 30 being held in the engaged position, the finger 28 maybe provided with a tongue, as shown at in Fi 1 which fits into a corresponding groove, formed in the finger 30.

As a matter of greater security but probably of less convenience I provide the modific'ation shown in Figures 5 and 6, in which the fingers 28 and 30 are replaced by a shaped locking clamp 50, this clamp having openings 51 thru which the projections 25 and 23 can readily pass. The shoulders 27 and 29 are, of course, omitted in this form. v

of lock which is operated by. placing the locking clamp about a spoke and forcing the v projections 23 and 25 thru the holes 51 looking them together. v

A convenient modification of my invention is shown in Fig. 7 in which double ended locking fingers and 71 are used. These looking fingers are free to turn in a similar manner to the fingers 28 and 30 and are restrained by collars 27 and 29. I

A still further modification of my invention is shown in Fig. 8 in which the lockingfingers are replaced chain having rings 81 of suifici'ent size to allow the proj ections 28 and 25 to pass there between. In

. practice the chain 80 is wrapped about the spoke 14 as shown in Fig. 9 and the projections are locked together thru the rings 81.

I claim as my invention: I 1. I A shackle for an automobile wheel c0mattached fin-.

prising a bumping block; arms for securing said block upon the tread of said wheel; projections on said arms meeting inside the telly of the wheel; means for locking said projections together; a finger pivoted to turn freely on one of said projections and engage a spoke; and a second finger pivoted on the other projection and cooperating with said first named finger to entirely encircle a spoke.

2. A shackle for an automobile wheel comprising a bumping block; arms for securing said block upon the tread of said wheel; projections on said arms in eting inside the folly of the wheel; means for locking said projections together: a finger pivoted to turn freely on one of said projections and engage a spoke; and a second finger pivoted on the other projection and cooperating with said first named finger to entirely encircle a spoke said fingers being mechanically interlocked with each other when said projections are locked together.

3. A shackle for an automobile wheel comprising a bumping block; a projection formed on said block and adapted to make a distinctive mark on the surface of the street it the automobile is moved with the shackle in place on a wheel thereof; arms for securing said block upon the tread of said wheel; projections on said arms meeting inside the telly of the wheel; means for locking said projections together; a finger pivoted to turn freely on one of said projections and engage a spoke; and a second finger pivoted on the other projection and cooperating with said first named finger to entirely encircle a spoke.

l. A shackle for an automobile wheel comprising a bumping block; a projection formed on said block and adapted to make a distinctive mark on the surface of the street if the automobile is moved with the shackle in place on a wheel tliereoi; arms for securing said block upon the tread of said wheel; projections on said arms meeting inside the telly of the wheel; means for locking said projections together; a finger pivoted to turn freely on one of said projections and engage a spoke; and a second finger pivoted on the other projection and cooperating with said first named finger to entirely encircle a spoke, said fingers being mechanically interlocked with each other when said projections are locked together.

In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 25th day of February 1920.
